Each year Fortune assembles about 50 of the top CEOs in the world for a dinner on the sidelines of the World Economic Forum in Davos, Switzerland. Of course this year, the annual event was postponed due to COVID-19. But Fortune still wanted to convene this group to discuss how business could best join forces to make a positive impact in 2021. How can all of us emerge from the global pandemic stronger than before? And today, on Leadership Next, our listeners are getting a special seat at that event. Before setting priorities for 2021, attendees heard updates on several of the most pressing issues of the moment: Pfizer CEO Albert Bourla spoke about the coronavirus vaccine efforts; Mary Barra of General Motors unveiled how her company plans to fight climate change; Facebook's Sheryl Sandberg offered a picture of tech regulation in the months ahead. Leadership Next's Alan Murray and Ellen McGirt bring you highlights from these reports. Also joining the conversation, the co-host of Fortune's Brainstorm podcast, Michal Lev-Ram.
